Review
This paper reviews recent data and concepts on metritis, purulent vaginal discharge (PVD), and endometritis in dairy cows and the ways in which these diseases affect reproductive performance. Metritis is characterized by fetid discharge from the uterus, with or without fever. Purulent vaginal discharge describes exudate that is >50% pus that may be attributable to uterine infection or cervicitis. Endometritis is inflammation of the uterus diagnosed by endometrial cytology with a proportion of neutrophils (typically ≥5%) that is associated with impaired fertility. Metritis and PVD are associated with uterine bacterial dysbiosis: changes in the microbiota to lesser diversity and greater abundance of pathogens, especially Gram-negative anaerobic bacteria, and Trueperella pyogenes in the case of PVD. Metritis is justifiably treated with approved antibiotics but criteria for more selective treatment without loss of performance are emerging. Purulent vaginal discharge is not synonymous with clinical endometritis, and greater precision in terminology is warranted. PVD is likely under-diagnosed and represents an opportunity for improved management in many herds. Endometritis seems in many cases to reflect persistent, dysregulated inflammation, for which the inciting cause is unclear. Postpartum uterine infection and inflammation have harmful effects on oocytes, embryo development, and the endometrium for at least three months, even if the disease is apparently resolved. Emerging concepts of the resolution and regulation of inflammation are promising for the improvement of prevention and therapy of endometritis.

Randomized Controlled Trial
BACKGROUND
Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is a clinical syndrome with various causes. It is not uncommon that COPD patients presenting with dyspnea have multiple causes for their symptoms including AECOPD, pneumonia, or congestive heart failure occurring concurrently.
METHODS
To identify clinical, radiographic, and laboratory characteristics that might help distinguish AECOPD from another dominant disease in patients with a history of COPD, we conducted a retrospective cohort study of hospitalized patients with admitting diagnosis of AECOPD who were screened for a prospective randomized controlled trial from Sep 2016 to Mar 2018. Clinical characteristics, course in hospital, and final diagnosis at discharge were reviewed and adjudicated by two authors. The final diagnosis of each patient was determined based on the synthesis of all presenting signs and symptoms, imaging, and laboratory results. We adhered to AECOPD diagnosis definitions based on the GOLD guidelines. Univariate and multivariate analyses were performed to identify any associated features of AECOPD with and without other acute processes contributing to dyspnea.
RESULTS
Three hundred fifteen hospitalized patients with admitting diagnosis of AECOPD were included. Mean age was 72.5 (SD 10.6) years. Two thirds (65.4%) had spirometry defined COPD. The most common presenting symptom was dyspnea (96.5%), followed by cough (67.9%), and increased sputum (57.5%). One hundred and eighty (57.1%) had a final diagnosis of AECOPD alone whereas 87 (27.6%) had AECOPD with other conditions and 48 (15.2%) did not have AECOPD after adjudication. Increased sputum purulence (OR 3.35, 95%CI 1.68-6.69) and elevated venous pCO2 (OR 1.04, 95%CI 1.01 - 1.07) were associated with a diagnosis of AECOPD but these were not associated with AECOPD alone without concomitant conditions. Radiographic evidence of pleural effusion (OR 0.26, 95%CI 0.12 - 0.58) was negatively associated with AECOPD with or without other conditions while radiographic evidence of pulmonary edema (OR 0.31; 95%CI 0.11 - 0.91) and lobar pneumonia (OR 0.13, 95%CI 0.07 - 0.25) suggested against the diagnosis of AECOPD alone.
CONCLUSION
The study highlighted the complexity and difficulty of AECOPD diagnosis. A more specific clinical tool to diagnose AECOPD is needed.

Purulent vulvar discharges, primarily caused by genito-urinary tract infections, are an important source of economic loss for swine producers due to sow culling and mortality. However, the agents that compose the vaginal microbiota of sows and their changes during infections are not well understood. The first goal of this study was to characterize and compare the vaginal bacterial content of healthy (HE, n = 40) and purulent vulvar discharge sows (VD, n = 270) by a culture-dependent method and MALDI-TOF MS identification. Secondly, we performed 16S rRNA targeted metagenomic approach (n = 72) to compare the vaginal microbiota between these groups. We found a wide variety of bacteria, with Proteobacteria, Firmicutes, and Bacteroidota being the most abundant phyla in both groups, as well as Escherichia-Shigella, Streptococcus, and Bacteroides at the genus level. Most agents identified in the sequencing method also grew in the culture-dependent method, showing the viability of these bacteria. Alpha diversity did not differ between HE and VD sows, regarding sample richness and diversity, but a beta-diversity index showed a different microbiota composition between these groups in two tested herds. ANCOM analysis revealed that Bacteroides pyogenes were more abundant in VD females and can be a marker for this group. Other agents also require attention, such as the Streptococcus dysgalactiae and Staphylococcus hyicus found in remarkably greater relative abundance in VD sows. Network analysis revealed important positive correlations between some potentially pathogenic genera, such as between Escherichia-Shigella, Trueperella, Streptococcus, Corynebacterium, and Prevotella, which did not occur in healthy sows. We conclude that the alteration of the vaginal microbiota between healthy and purulent vulvar discharge sows, although not extreme, could be due to the increase in the relative abundance of specific agents and to associations between potentially pathogenic bacteria.

.We present the case of a 46-year-old female with dysphagia to solids and retrosternal pain that worsened after eating. Due to mediastinal lymphadenopathies, she underwent endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) 3 weeks before, mentioning the complaints started afterwards. On physical examination she had fever (38.3ºC). Gastroscopy revealed three 10-20mm fistulous orifices with purulent discharge at 26-32cm from the incisors and another four partially covered by fibrin in the distal esophagus. EBUS-TBNA report was reviewed, mentioning 6 needle passes through the esophagus, due to failed endotracheal intubation, without immediate complications. A cervicothoracic CT scan identified 2 mediastinal abscesses, the largest with 9cm, communicating with the esophageal fistulas. She was admitted, underwent intravenous antibiotics and endoscopy-guided nasogastric tube placement. The histopathological analysis diagnosed Castleman's disease. There was clinical and imagological improvement during admission. After 16 days she was released. Upper endoscopy was repeated one month later showing complete closure of the fistulous orifices.

Brazilian Journal of Otorhinolaryngology 2022Actinomycosis of the nasal cavity is very rare.
INTRODUCTION
Actinomycosis of the nasal cavity is very rare.
OBJECTIVE
The purpose of this study was to investigate the clinical features, treatment methods, and treatment results of actinomycosis of the nasal cavity in our hospital.
METHODS
We retrospectively enrolled 11 patients with histopathologically identified actinomycosis of the nasal cavity from January 2010 to May 2020.
RESULTS
This study included five males and six females. The most common symptom was purulent nasal discharge (36.4%). Nasal actinomycosis occurred in the maxillary sinus in 5 (45.5%) patients, the ethmoid sinus in two, the hard palate in two, the frontal sinus in one, and the nasal septum in one. After surgery, intravenous administration of antibiotics was performed on average for 7.4 days and oral antibiotics were prescribed for about 120.5 days. The clinical characteristics of the patients with nasal actinomycosis and the duration of antibiotic usage were not significantly different. Trauma was significantly associated with repeated nasal actinomycosis infections (p < 0.05).
CONCLUSION
Actinomycosis of the nasal cavity should be suspected when a patient with chronic sinusitis does not respond to medical therapy and has a history of dental treatment, local surgery or radiation therapy. Nasal can be sufficiently treated with antibiotics and endoscopic surgery.

Review
Endophthalmitis is a condition of the eye caused due to complications in cataract surgery. The extent of this complication can be from minor to very serious, leading to a permanent loss of light perception. It is generally an inflammation of the fluids present in the anterior and posterior chamber of the eye, consisting of vitreous and aqueous fluid. The inflammation is due to the infection of these fluids after their exposure during or after the cataract surgery. In today's situation, patient surgery is the most frequently preferred for the correction or treatment of the cataract. There are various factors causing endophthalmitis in cataract surgery. This condition occurs mostly by the entry of infective bacteria such as staphylococcus, gram-negative organisms, and streptococcus species. As well as fungi like aspergillus and candida. Cataract surgery has many risk factors that can be divided into preoperative, intraoperative, and postoperative phases. The most common symptom of this condition is pain in the eyes and redness, which sometimes leads to purulent discharge, causing decreased vision or loss of eyesight. The increasing inflammation of the vitreous fluid is the main identification of the condition. There is a surge of inflammatory cells in the space of the vitreous fluid. The condition can be classified into two types which are exogenous and endogenous. In these types, subtypes explain the postoperative complications of the disease. It is a rare condition, and the percentage of it occurring as a postoperative complication is very low. It generally targets the old age group of people. This narrative review article explains endophthalmitis as a postoperative complication of cataract surgery and its treatment modalities. The terms endophthalmitis, postoperative, cataract surgery, complications, and vitreous humor were used for the review article in PubMed.
